How can I find out what kind of fish are stocked in a certain stream or lake?

On the Fish and Game web site, www.state.id.us/fishgame, select "Fishing" then "fish stocking." The next page will give you a link to information about where fish will be stocked this year, another to stocking history, and one to hatchery information. In the stocking history page, you can select a search by species, the name of the stream or lake, the county or the hatchery.
